Building a Homebrew Load Box

Hamza Salman Afzal - Applications Engineer Aug 21st 2013
Recently, I sent out a circuit prototype for testing at a certification lab. After a few days I called to see how it was going and discovered that testing was delayed. They did not have an electronic load with which to conduct the tests. While electronic loads (we call them “load boxes”) are a common sight in any ...

LT1001 Precision Current Sink

Nov 1st 1983
A non-inverting amplifier configuration can force an input control voltage across a ground referred resistor. This creates a precise amount of current flow. This current must be sunk by the external transitors so the same amount of current flows to ground from a positive supply referred load circuit. ...
